Referring to the embodiment of my invention illustrated bythe drawings,I have shown fa button which .is particularly adapted to be secured togarments or other v material bymeans of a? metallic fastening deviceturned'and concealedby anv anvilportion inthe button.` p i Hcretoforebuttons ofthis. class have been formed from sheet metal. and also yfromv solid bar stock.y The Vsheet metal buttons y have been ormed-withabody part and a separate anvil part securedrin various yways to thebody part. Therefore, at least two separate pieces were required toprovide the bodyand anvil portion. Buttonsapresent- Y ing one-piece bodyand` anvil portions have heavy vas compared with a sheet metal but- Yton.

My invention, as illustrated by the drawings, isdirected toa sheet metalbutton which has the'anvil or turning and clenching means formedintegral withy thev body part of the button and also relatesto themethod of making such a button.

The button illustrated vby Figs. 1 and 2 has a body portion whichincludes the headk 1 (being the part which passes` through kabuttonhole), a cup-shaped shank 2 Vformed Yintegral with the head, andananvil 'por-v In this instance I have shown (Figs. 2 Aand Y 4) a tack6which mayl be of anysuitable structure, piercing. a suitable vcarryingmedium 7 and having its pointed end portion with thel inturned doublewall portion 4 to hold the button' in place upon the carrying medium '7.f 1

tack from piercing lthe anvil portion. When the attachment is completethe shank of the tack is concealed and the button presents a neat andfinished appearance and therel is no portion ofthe tack exposed whichmay. rust Referring now to the method 'of making the body portion withthe integral anvil,- as shown inV stepbystep Vform inrFigs. through 13,I havey illustrated various which perform the various operations. Thefiat blank shown in Fig.,5 is first passed be tween the dies 11 and 12(Fig. 6) which cup the blank, as shown in cross-section.' Thecup-.shaped part then passes between dies land 14, vshown in Fig. 7where the head and cupshaped shank 2 are formed InV this form itispassed between the dies 15 and 16 (Fig. 8) and the vbottom of thecupshaped shank 2 is pressed toward the open end of the cup to begin theVformation of the anvilor clenching and turning means. The blank nextpasses between thedies 17 and 18 `(Fig. 9) and the dies 19 and 2O (Fig.10) to complete the process ofpressing the lbottom of the cup-shapedportion toward the mouth of the shank and form the double thickness wallportion 4. In Fig. 11, the V,dies 21 and 22'turn the wall portion 4 in-J wardly toward'the center of the shankv and against the projection 23on the die 22 to form the restricted opening 4a surrounded I bya'substantially' perpendicular wall.V The button is complete at Vthisstage, but I prefer to'provide the head 1 with a rounded flange '24, soI pass it from between the dies 21 and 22 through the dies 25 and 2oV(Fig. 12)` and between the dies 27 and 28' (Fig. 13) where the flange iscompleted vand the button is then turned out Complete from a singlepiece of sheet metal.

VMy improved button and the method of forming thevsame aife'simple and,while I have shown a complete oneepieoe sheet metal button, Vmyinvention is more-particularly directed to the formati-on ofthe anvilmeans as an integral part'of the body of a button which is pressedfromsheetA metal. he shape of the head 1 of the body may be varied.preferred forms being shown in l Figs. 2 and 3. rlhe head of the bodymay be'covered by another piece ofmetal or fabric or the like ifdesired, preferred forms being shown by Figs. 14 and 15 and in myapplications hereinbefore referred to as filed herewith'. f

While I have illustrated and described my invention somewhat in detail,I do not wish to be limitedthereby as the rscope .of my invention isbest definedin the following claims.

Claims: 1. YA metal button having a body formed of sheet' metal, saidbody having as integrai rparts thereof, av head, a'shank having .aredies'.
